kernel panic && 3.6.9

[rolan]

Till last patches (grsecurity) for kernel 3.6.8 perfectly fine
everything; starting from kernel 3.6.9, kernel panics. May it be
connected with the fact that I am on 32 bit? (Distro = slackware
current.) I also don't have tried yet to build 3.6.9 -- without
grsecurity support.

can you post the details of your kernel panic? also your config/vmlinux/bzImage may be helpful.

3.6.9 vanilla <=> zero problems by the way. Okay, I will collect
what you demand; what did so drastically change between the 3.6.8
and the 3.6.9 grsecurity patches series? Every 3.6.8- patch did
work, and none of the 3.6.9 does. (I am also not using virtually
anything from sysvinit, by the way, and even less from systemd! I
am using s6 && tools; and my kernel is monolithic, though it
should not matter.)

i also get kernel panic during early boot time since 3.6.9, hopping that rolan's experience is same i will just throw my stuff on this post
sadly no serial connection and it hangs too early for netconsole

The system is working properly, I did not notice any problems.
